I just finished building up my b18a with p30 pistons. It should be around 11:1 compression and I was wondering what kind of spark plugs I need to use with this set up. I have read a couple of searches and most are about vtec heads. I dont know if that changes anything or not, but any help is appreciated.

 

im using autolites from autozone

 

use the stock NGKs for a GSR

 

thanks anyone else? is anyone running this setup?

 

NGK BKR7E

 

the OEM LS plugs are NGK zfr5f-11

you can go one step colder on the same style plug to the zfr6f-11.

 

thanks for the help guys

 

I'd go with a heat range of 7. 6 is a stock B16/B18 heat range, with the added compression over stock go with 7s. I use NGK BKR7E-11s.. only $1.89 or so per plug.

 

just wondering what the benifits are of using 7's .....

I'm at 11.4:1(B17/ctr) and I'm using BKR6E-11 with no problems..... am I doing damage to my engine by using these plugs or am I losing power because of them.....pls enlighten me.... thanks..

autolite plugs for imports aren't as good as they are for domestics... so

 

You will loose power if you run 7s with that low of compression. Use the same NGK plug that the stock 11/1 type-r uses, its a #6.
